COMBINED CUT-OUT VALVE, PRIMING DEVICE, AND AUXILIARY AIR INLET FOBINTERNAL-COMBUSTION ENGINES.

Application filed March 29, 1922. Serial Ito/547,808.

To all whom it may concern:

'Be it known that I, JAMES C. AKINs, a citizen of the United States,residing at Beckville, in the county of Panola and State of Texas, haveinvented certain new and useful Improvements in Combined Cut-Out Valves,Priming Devices, and Auxiliary Air Inlets for Internal-CombustionEngines, of which the following is a specification, reference being hadto the accompanying drawings.

This invention relates to improvements in a combined cut-out valvepriming device and auxiliary air inlet for internal combustion engines.4

An important object of the invention is to provide a device which may beseparately employed for accomplishing the above objects and whichconsists in a simple mechanism'disposed intermediate the intake manifoldof the engine and the cut-out valve of the exhaust. v

A further object of the invention is to provide a device of thischaracter which is extremely simple in construction and operation,efficient and durable in service and a general improvement in the art.

These and other objects I attain by the construction and arrangementshown in the accompanying drawings wherein for the purpose ofillustration is shown a preferred embodiment of my invention and whereinlike reference characters designate like parts throughout.

In the drawings:

Figure 1 is a diagrammatic view showing an apparatus constructed inaccordance with my invention applied to an internal combustion engine;

,Figure 2 is a side elevation of the control valve;

Figure 3 is a section on the line 33 of Fi ure 1;

igure 4 is a vertical section taken through the cut-out valve operatingcylinder;

Figure 5 is a section taken through the cut-out; and

Figures 6, 7 ,"8 and 9 are sectional views showing various positions ofthe valve to give the various connections desired.

Referring now more particularly to the drawings, the numeral 10indicates an enof the usual construction. These valves,

.as is well known to those familiar with the art, embody a flap valve 16movable to close an opening 17 or to close the exhaust passage of theconduit 13 and direct the gases thereof through the opening 17 into theopen air. These valves are provided upon the stem 18 thereof with anoperating lever 19 and the valve is held in closed position by means ofa spring 20. I

In accordance with my invention I provide a cylinder 21 having shiftabletherein a piston 22, the rod 23 of which is connected, as by a link 24:,with the operating lever 19 of the cut-out valve. The piston of thecylinder is so arranged that the piston is at one end of the cylinderwhen the cut-out valve is in its closed position.

The numeral 26 designates a control element in the present instancedisclosed as a three way valve having one port thereof connected by aconduit 27 with the intake manifold, a second port connected by aconduit 28 with the end of the cylinder 21 remote from that at which thepiston 22 is disposed when the cutout-valve is closed, 35 and the thirdport of which is connected with a priming cup 29. Itwill be seen thatwhen the valve body 30 is so arranged that the main port 31 thereofconnects the conduits 27 and 28 the suction within the intake manifold11 will create a vacuum within the cylinder 21 causing the piston to hedrawnupwardly and by reason of its connection with the arm 19, to openthe cutout valve against the action of the spring 9 20. If the valve isnow rotated so as to connect the branch port 32 thereof with the outletat which the conduit 28 is connected, the main port 31 will be inconnection with the priming cup outlet and air Wlll be admitted to theconduit 28 permitting the piston to return to its normal position underthe action of the spring 20. If the valve is positioned so as to connectthe priming cup with the intake manifold it will be seenthat the primingcup may be employed either for the admission of fuel to assist instarting the engine or for the admission of air during operation of theengine to alter the ratio of the combustible mixture admitted to thecylinder. The control member 26 may be arranged at any desired point,preferably upon the dash D of the vehicle where it will be readilyaccessible to the operator.

While I have in the present showing disclosed a three way valve foraccomplishing the connections desired, it will be understood that I donot wish to be limited to such specific structure, for this constructionmay be altered in many ways without in any manner departing from thespirit of my invention, nor do I wish to be understood as limitingmyself to the specific arrangement hereinbefore set forth, as the sameis likewise capable of many changes and I accordingly do not limitmyself thereto except as hereinafter claimed.

I claim:

1. The combination with an internal combustion engine, embodying the"usual intake; manifold, exhaust manifold, and muffler connected to theexhaust manifold to receive the exhaust gases therefrom, of a cutoutvalve arranged intermediate the. muffler and exhaust manifold, acylinder, a piston reciprocable within the cylinder, a. connectionbetween the piston and the cut-out valve whereby the cut-out valve isoperated upon reciprocation of the piston, and a connection between oneend of the cylinder and the intake manifold of the engine.

2.

3. The combination with an internal combustion engine embodying theusual intake manifold, exhaust manifold, and mufiier connected to theexhaust manifold to receive the exhaust gases therefrom, of a cut-outvalve arranged intermediate the muffler and exhaust manifold, acylinder, a piston reciprocable within the cylinder, a connectionbetween the piston and the cut-out valve whereby the cut-out valve isoperated upon reciprocation of the piston, and identical means forconnecting one end of said cylmder with the intake manifold of theengine, Or with the atmosphere and for connecting the intake manifoldwith the atmosphere.
